Does anyone have or had a numbness in left hand ring finger, pinky finger down to the palm at side of hand? I have had this since open heart surgery CABGx3 8 months ago. Heart surgeon said wait 6 months, now it's wait 12 months, then see a neurologist. They say its some kind of nerve damage, your arms are pulled above and behind you during the surgery, or from pulling the chest open and stretching everything??? its not painful, just a nuisance except for guitar playing with the left hand required to make chords and typing on a computer.
